Book of Blood

In a diner, Wyburd watches Simon and lures him into his truck. Simon is knocked out and wakes strapped to a table, where Wyburd offers a choice between a slow death or a quick, clean one by telling the story of the Book of Blood. Simon agrees to reveal his story as the price for a fast end.

Strapped to a table, Simon begins to recount the events that shaped him, promising that the dead will write their tales on his body. He frames the 'Book of Blood' as a living record of scars and memories. The bargain marks the literal start of the possession of his life by the dead.

A teenage girl is violently raped and killed in her bed, while her parents scream outside. The brutal act seeds the house's dark past and the ghosts it will unleash. This event becomes the catalyst for the investigators who arrive later.

Paranormal professor Mary Florescu and her partner Reg Fuller arrive to uncover the house's murderous history. They move in with Simon, who is briefly presented as a clairvoyant ally. The trio sets up a field study to observe the escalating hauntings.

Mary encounters Simon and is drawn to him as his abilities seem uncanny. They grow closer and eventually become lovers, complicating the investigation. The emotional bond deepens even as the supernatural events intensify.

During the investigation, Mary hallucinates six girls dancing in a circle. When the dancing stops, the figures vanish and reveal themselves as ghosts watching her. The sight confirms the house's supernatural grip.

Reg persuades Mary to send a sample of the walls for analysis, and the lab returns with gunpowder residues. The discovery shows that some phenomena may be staged tricks rather than pure haunting. Mary realizes Simon may be deceiving them, even as she suspects hidden powers.

Mary confronts Simon, who admits some deception but argues that not all events are fake and that the house has chosen him. He hints that Mary herself could be the mechanism that awakens the ghosts. The tension escalates as trust fractures within the trio.

The hauntings intensify, with dragonflies appearing and specters closing in on Simon. Reg moves to intervene but is tormented by a terrifying ghost and falls to his death. Mary faces the escalating madness and the possibility that the house will overwhelm them.

Mary declares that the house is an intersection that allows the dead to spill over into the living world. She asserts that Simon has led them to this crossroads, but Reg argues it is not just Simon's doing. The revelation reframes the threat as a test of who will listen to the dead.

The ghosts return to torment Simon, carving wounds into his flesh with nails and glass. Mary races to find him as the spectral descent continues down the stairs. The room fills with fear as the past presses in.

Mary pledges to listen to the dead and helps the spectral procession depart, allowing Simon to survive the ordeal. The house finally releases its hold as the ghosts withdraw. Yet the Book of Blood remains, and Simon's flesh still bears the living stories.

Simon confesses that he has been kept prisoner, the book on which the dead write, and that Mary has profited from his stories. He explains that Wyburd was hired to strip his skin in exchange for payment. The grim confession links the past and present in the tragedy.

Wyburd follows through on his bargain and kills Simon quickly after retrieving his skin. He places the skin in a suitcase and awaits payment that never arrives. The macabre turn intensifies the sense of fatal bargains.

Blood floods the building as the suitcase leaks, and Wyburd drowns in the rising tide. Mary arrives unfazed, opens the suitcase, and finds Simon's intact skin. She smiles as she begins to read the stories still being written on the living book.
